Analysis of the Relationship Between the Electrical Properties of the Tube Wall and Weight Function Based on the Finite Element Method
摘要
Abstract
The weight function represents the relative contribution of the fluid velocity at particular spatial location in the flows cross section to the output signal of the flow meter. The theory of weight function is one of the important parts of the theory of electro?magnetic flow. Solving the weight function is important for inferring the velocity distribution. Based on the virtual current theory,the weight function of the electromagnetic flow meter with the non-insulated pipe wall. In this paper,the influence of electrical charac?teristics of non-insulated pipe wall on the distribution of weight function is calculated and weight function distribution maps are giv?en. When the flow distribution is extremely unbalanced,the method can be further used to analyze and calculate the velocity distri?bution in a fluid flow sensor with special structure. It is also the first step of image reconstruction.关键词
